Thanks, I'm the architect, project manager and surveyor so it is a lot of detail to keep track of. Some mistakes made and lessons learned but nothing too bad so far.

In the years (

) that I have had planning my room (constructed very similarly to yours), I have gone back and forth between recliners and lower back couch-type seating. I know there are a couple options for low back recliners, but there are not enough IMHO...and the ones that are available are very expensive!
My plan is to build the ceiling with 25 x 1 tonne rated cargo hooks and get some of these :
https://www.amazon.co.uk/Amazonas-AZ.../dp/B00GRYFB20 (they really are very comfortable) and/or these
https://www.alfresia.co.uk/porto-ste...egg-chair.html paint them black (where necessary), install low power local LED lights, and hang them from the ceiling. Eight hanging seats would form the upper / main tier and I could bring in some low seats in front for large groups (or even bean bags for the kids).

Similar low-profile aspects of my build will be no front stage and slender surround speaker columns....will be employing can lights, AT screen, and some sort of method to hide the projector though.
If you're doing a from scratch build, have you considered rear projection? The modern screen materials don't show significant blur at a decent screen size and the ability to maintain high contrast ratio with house lights on is a trick no conventional design can match. The major issue is usually lack of projection space (or rather unwillingness to give up room size / seat count for projection space). In a custom build though you can bend it under the floor or ceiling, or just extend the building.

I am concerned for your 24x24x9 dimensions...lots of ringing built into that geometry...but hoping you can mitigate it via acoustic treatments/processing.
My plan is quarter inch solid rubber 'slate effect' (textured) jet black tiles on floor, ceiling and walls, backed by 1/2" drywall, mounted on steel studwork spaced 9" from the walls. I will put eggcrate sound insulation on the steel walls before the false walls go in and rubber strips under the studwork fixing U channels. The ceiling will be suspended 4" below the beams (which will be half-embedded in the slab), 12" below the bottom of the slab, with that cavity filled with rockwool. Since I don't need decoupling, just low frequency reflection dampening, thick rubber washers should suffice. Floor will be 4" solid foam insulation, 2" screed with heating pipes, quarter inch carpet underlay then quarter inch rubber tiles.
Square geometry is still not ideal for acoustics, but that is strongly preferable for some other uses of the room.
